The Withings Pulse O2 monitor does all the activity monitor basics and then some: It measures steps taken, distance traveled, calories burned, sleep quality and pulse. But what makes this device special is its elevation monitor and blood oxygen sensor aimed at climbing enthusiasts and asthmatics.

Withings is clearly tapping into a limited market – so far, oxygen sensors are far from standard activity monitor features. If keeping an eye on your oxygen saturation level (SPO2) comes at a premium to you, then the price here sounds just about right.

The Withings Pulse O2 is currently available through Withings.com for $119.95. To learn more, you can watch the promotional video below.
